Kauno autobusų gamykla (transl. Kaunas Bus Factory), abbreviated KAG, was a factory in Kaunas, Lithuanian SSR that produced about 10,000 KAG-3 buses from 1956 to 1990.[1] The buses used chassis of the GAZ-51 truck. The factory then added wooden frames covered with metal sheets. It was the only mass-produced vehicle in Lithuania.[1]
The factory was established in an old workshop owned by Amerikos lietuvių akcinė bendrovė [lt] (Lithuanian American Joint Stock Company), abbreviated as Amlit. The company imported Ford cars, Fordson tractors, and bicycles.[2] Around 1929, it started building passenger buses with wooden frames based on Ford chassis. About 25 buses were produced per year.[3] The company was nationalised after Lithuania was occupied by the Soviet Union. After World War II there was a shortage of vehicles and metal. The auto shop, then known as Kauno autoremonto gamykla, started modifying ZIS-150 trucks into L-1 buses that were first designed and produced in Leningrad in 1949.[4][5]
In 1952, the factory started building KAG-1 passenger buses, which were copies of the Russian GZA-651 buses and were built on the GAZ-51 chassis.[5] The factory improved the model and developed its own KAG-3 bus, though it retained essentially the same specifications.[4] The buses had a six-cylinder, 68 horsepower, 3.5-litre engines. An empty bus weighted 3,890 kilograms (8,580 lb).[1] KAG-3 was the most popular model, with up to 350 vehicles produced per year.[5]
The wooden frame would rot over time, which is why only a couple buses have survived. Examples are preserved in museums in Kaunas and Vievis, as well as by a classic car club in Kaunas.[1] The wooden frame could also easily catch fire in an accident. One of the largest accidents occurred in winter 1966, when a crowded bus drove into a ditch and caught fire on the road from Luokė to Smilgiai. 21 people died in the accident, four others suffered severe burns.[1] Due to safety concerns, the buses were phased out from passenger transport and converted into cargo or utility vehicles.[4] However, the KAG buses remained in demand even after metal frame buses (such as PAZ-652) became available. The wooden frame could be replaced (some buses had 3 or 4 frame changes) and performed better on uneven roads (such as roads of the Caucasus).[4]
